Apparatus and method for seaming
material with hot melt adhesive

ABSTRACT

AN APPARATUS AND METHOD FOR BONDING PLIES OF SHEET MATERIAL, ESPECIALLY FABRIC MATERIAL, USING A HOT MELT ADHESIVE ARE DISCLOSED. AN IN-LINE SEQUENCE OF OPERATIONS INCLUDES BRINGING A PLY OF SHEET MATERIAL INTO OVERLYING, ALIGNED POSITION WITH ANOTHER PLY, APPLYING A BEAD OF HOT MELT ADHESIVE TO ONE OF THE PLIES AT A POSITION WHERE THE SEAM IS DESIRED, AND FINALLY PRESSING THE PLISE TOGETHER PRIOR TO SOLIDIFICATION OF THE ADHESIVE TO CAUSE THE HOT MELT TO PARTIALLY PENETRATE THE PLIES. PROVISION IS MADE FOR QUICKLY   AND ACCURATELY BEGINNING AND TERMINATING THE BEAD OF HOT MELT ADHESIVE.

Int. Cl. B29c 27/10 US. Cl. 156-202 4 Sheets Drawing. 16 Pages Specification An apparatus and method for bonding plies of sheet material, especially fabric material, using a hot melt adhesive are disclosed. An in-line sequence of operations includes bringing a ply of sheet material into overlying, aligned position with another ply, applying a bead of hot melt adhesive to one of the plies at a position where the seam is desired, and finally pressing the plies together prior to solidification of the adhesive to cause the hot melt to partially penetrate the plies. Provision is made for quickly and accurately beginning and terminating the head of hot melt adhesive.
